Q: Why do complex plastic profiles for LEDs have high requirements for precision plastic extrusion? A: LED profiles often need to have precise optical light-guiding structures and heat dissipation channels, and dimensional errors will directly affect light efficiency and heat dissipation performance. Precision extrusion can ensure that the dimensional tolerance of the profile cross-section is controlled within ±0.1mm, meeting the assembly precision requirements of LED components.
Q: How to solve the problem of insufficient optical performance of complex plastic profiles for LEDs? A: First, high light transmittance PC or PMMA raw materials should be selected to reduce light loss; second, optimize the polishing process of the optical surface of the mold to achieve mirror-level surface finish; at the same time, adjust the extrusion temperature and cooling rate to avoid light scattering caused by internal stress generated inside the material.
Q: What to do if LED profiles have poor weather resistance when used outdoors? A: Anti-UV additives and antioxidants can be added to the raw materials to enhance the anti-aging ability of the profiles; adopt co-extrusion process to cover the surface of the profile with a layer of material with better weather resistance; in addition, perform surface coating treatment on the finished product to form a protective film, which can effectively resist erosion from environmental factors such as ultraviolet rays and rainwater.
